It will sometimes happen to me on requiem but restarting the map usually fixes it. So I don't understand.

Didn't fix anything. Still missing the gun, Corruption of textures. Should I try to uninstall WaW and t4m and then reinstall all of it?

Trying to load into the map my graphics are all corrupted and stretching all over the place and I can't see anything. T4M is installed and tried launching it using the UGX mod manager and the in-game mod list. Nothing fixes it. Tried to reinstall T4M and it didn't change anything.
